Detection of AI-2 activity via bioluminescence assay of V. harveyi BB170 incubated with culture supernatant of A. hydrophila in the absence (control) and presence of the inhibitor (−)-Dimethyl 2,3-O-isopropylidene-l-tartrate. The bioluminescence measurement was performed seven hours after the addition of the inhibitor. Bioluminescence was lower than that of the untreated control (p < 0.001 *** and p < 0.05 *). The error bars were calculated using a standard error of mean (SEM). A.h (A. hydrophila wild type).
